IMPROV'ED GAR-BRAKE.

TO WHOMl IT MAY CONCERN: ,l

Be it known that we,GEOBGE QUICK and JOHN WALLIS, of the tbwn of Fleming, in CayugacountL--New p York, have invented a new and improved Mode of Applying or Operating the Brakes onRailroad-Cnrs; and we do hereby declare the following lso be a full, clear, and exact description of the seme, `reference being had to the accompanying' drawings, makinga part of this specification, and to the letters of reference markedfther'eon. f

'The'object of this invention is for the purpose of arranging certain, mechanical devices in such form and manner that the force or momentum ofth'e cars when in motion will operate or apply the brake of saidcars, so i as to overcome the velocity of the same.

Andin order that others skilled in the art mayy know how to make and use our invention, we will proceed i to describe its construction and mode of operation.

Figure 1 is o. perspective view of two cars, with the several parts of said bra-ke attached thereto. I

Figure 2 is a representation of the brake. l p .p In iig. 1,'A is the brake-reihe vertical cross-section of which is shown at Figure 3. `Saidrodis'srconnected.

together between the curs with a link, R, Figure 5, in the usual manner. In fig. 2, D DD D are the brakeblocks, which act against the car-wheels. E E are the brake-bars, for supporting and holding thel brake-blocks .D firmly in their places. On both ends of the said bar are tenons, F. These are mortised through the frame;

work of thecar, asv shown at (Land are allowed, by means of the length of the said mortises, to slide suffi-` ciently to allow the brnke to act'against the wheels when the force is applied thereto. On-the brake-bars E are i four stands, H, I, J, K. Through the stnnds'H and I passes the lever L, and through the stand J -and passes 1 tho lever M. The lever L is jointed to the stands H and I, and the lever M to the stands J und K. The levers L and M pass up through the edges of the brakcfrod A, as shown at N, and are operated. by the shoulders O and P, as hereinafter described. .The cam-rods C C extend through the entire length of the cars on bothjsides of the brake-rod A, and nre let into the same, as shown at Q, und slide therein.

Figure 3 isa cross-section of this br'nk'e-rod A, and C C are sections of thetccm-rod.- Into each ot` the said cam-rods C is cut a notch, S, as shown :it Figure 4. When placed in the proper relationsto therbrake-rod A, seid notch comes opposite, or nearly so, tothe notches in the brake-rod at N.

. Figure 6 shows themode of connecting or coupling the cars together. 'l 'l are hunters, U are the linkbolts. V is a latch or hook, jginted at W to the cam-slide C', and lroolee'd into the cam-slide Cfon the other cnr. At Y part of said hook is shown in dottedlines, itbeipg dropped into the place and the point out of sight,

The key Z is shown at Figure 7. "he web of the lcoy A lies under the latch V,'and has its lbearings Bl i A B on both Asides thereof, on. the cum-slide C. The object or use oi' the key Z is to lift out the hook V, by turning the Wcb'A of the key into :t vertical position by the handle D. New, `ifhthe cars are to move `in the direction of the dart on the broken-od A, the cern-slide C on this side must be drawn forward-a distance Sullicient to lift out the lever L from the notch on this side of the brake-rod A, and thoicnrs can movel in the direction above indicated without affecting the brakes. But whenever it becomes requisite to stopthe train (the locomotive being reversed) the broke-rod will be slid bock, carrying with it the upper end of 4the levers M M, and by the connection ,of the scid lever with the brakes ebovedeseribcd -the brakes will be directly applied to thewheels on all the cars so connected together bylncans of the force or momentum of said curs. The spirarl i springs E E', `connected to the brake-bars E, are for the purpose of relecsiugthe brakes from the cur-wheels when no t in usc. The rubber springs F F are connected nt ono end with thcwcam-slideC, and at the other with the framework oi' the truck, and their object is to hold the cam-slide C 4in its normal condition.

Having above described the mode of constructing and operating our invention, what we cluim as new, and wish .to secure by Letters Patent, is- M v .1. The brake-rod A, levers L und M, thc'stnnils H,\I, J, K,`\\il1en constructed ns und for the purpose specified. 2. The cam-slide C, and latch V, ond key Z, when constructed in the, manner and used for the purpose oveset forth. GEO. QUICK,-

JOHN WALLIS.
